Who Is The Greatest NBA Championship Team Ever?

The latest version of the Boston Celtics is being considered as one of the all-time great title teams in NBA History. I don't feel that way but hey, I just write about this stuff.

With that in mind; who do you consider the greatest NBA Championship team in a single season (No dynasties) in your lifetime. Is it the 1996 Chicago Bulls, who went 72-10? Was it the 1986 Boston Celtics, the 1985 Lakers or the 1989 Bad Boys of Detroit? Maybe it was my favorite: the 1983 Philadelphia 76ers.
